Brief icy conditions possible tomorrow morning

As high pressure slides to our east tonight, winds will turn to the southeast, adding moisture to the low levels. A storm system currently moving through the Midwest will track into the Great Lakes region tonight, pushing a warm front toward the region from the southwest, providing a focus for lift and light precipitation.

Forecast soundings indicate a dry layer above the lower moist layer which is a classic indication of drizzle. Surface temperatures will start off in the 20's tonight, and rise into the low 30's by mid morning, allowing for freezing drizzle. As mid levels moisten a little more by noon, we may see brief light snow in central and northern NH, before flipping to rain.

No accumulation is expected, and this likely will not pose any issues. Just a heads up.

Looking ahead, adverse weather conditions appear likely for Thursday (Thanksgiving) night into Friday. Wintry precipitation is a distinct possibility, although there're still equal chances that it turns out as all rain. More details (and more confidence in those details) tomorrow.
